The BlastIR USB IR repeater kit allows you to use an existing remote control to operate up to four AV components located behind in the rear the room, in a cabinet, an equipment closet, or anywhere else that is out of sight. IR distribution technology allows you to conceal all of your bulky entertainment equipment, like your cable box, satellite receiver, stereo, amplifier, Blu Ray player, and more without losing the ability to control it with your remote.

The BlastIR USB repeater kit is dual band, which means it will work with the most IR devices. You can power the BlastIR USB with the USB port on your HDTV, giving you a clean look and an easy install. If your TV doesn’t have a USB port, simply use the included DC12V adapter. This compact BlastIR is perfect for a simple installation in which you are only hiding away a few devices. If you need to control multiple devices with more options, check out the full sized BlastIR Pro.

Ir Guide

How it Works

The BlastIR USB consists of an emitter cable, a receiver, and a USB power cable. The receiver is a small, easy to hide device that you can mount on or near your HDTV. Keep in mind that the receiver must be in the line-of-sight to wherever you will be using your remote control.

The receiver picks up your remote’s IR signal and transfers it over a small cable to the emitter. The emitter can be placed directly over the IR sensor on the device you wish to control.

The USB cable either plugs into the USB port on your TV, or you can plug it into the included DC12V adapter to power the BlastIR USB.

The length of the cable between the emitter and receiver is 6 feet. The length between the USB power connector and the IR receiver is also 6 feet, so the combined length of the product is 12 feet.

Works Good

I bought a single blaster and had to call support to find out which part was the sender and which was the receiver. The instructions did not state which was which. After that was resolved it works very well.

Great Product

Pros: I just had a cabinet built and wasn't sure how to hide my components. I had no idea what I needed. Sewell Direct had so much information and helpful videos that I felt confident I had purchased the right product for my needs. Cons: noneOther: The packaging is superior. It looked like a pretty Tiffany box. I know this might sound dumb, but it made me feel like this company is very proud of their products.
